Pressure switch
KP
The KP pressure switches can be used as safety
switches against too low a suction pressure and / or
too high a discharge pressure in refrigeration and
air conditioning systems. They can also be used
to start / stop compressors and fans for air-cooled
condensers.
They are available in both single and dual versions
and include a single pole double throw (SPDT)
switch.
Features • Ultra-short bounce time thanks to snap-action
function (reduces wear to a minimum and
increases reliability)
• Available with gold-plated contacts
• SPDT switch design
Offers open or close switching action on pressure
rise or fall
• Fail safe double bellows
Prevent refrigerant loss and system
contamination - standard on KP 7 and KP 17
pressure switches
• Convenient manual trip feature
To test electrical contact function
- no tools needed

Enclosure
~NEMA 1
This grade of enclosure is obtained when the units
without top cover are mounted on a flat surface or
bracket. The bracket must be fixed
to the unit so that all unused holes are covered.
~ NEMA 2
This grade of enclosure is obtained when the units
with top cover are mounted on a flat surface or
bracket. The bracket must be fixed to the unit so
that all unused holes are covered.
